Abstract :
A 1.5 V bootstrapped BiCMOS (BS-BiCMOS) logic gate is presented. This design represents the first attempt to operate at a 1.5 V supply voltage without using complementary bipolar devices or MOS threshold voltage adjustment. The use of the bootstrapping technique described here provides a transient logic swing of 1.1 V and a 70% speed improvement over previously reported low-voltage designs.
